Ce dispositif est pourvu de logements de transport dans lesquels les pièces en acier sont disposées et lesquelles sont configurées pour le transport de pièces en acier à des températures supérieures à 650°C. L'invention concerne en outre un procédé de transport de pièces en acier par un dispositif permettant de chauffer les pièces en acier en direction du dispositif de chauffage, de formage à chaud ou de trempe à la presse des pièces en acier, la pièce en acier étant chauffée au cours d'une première étape dans un dispositif de chauffage à une première température prédéfinie supérieure à la température ambiante. L'invention vise à fournir un dispositif et un procédé de transport de pièces en acier, lesquels garantissent que les températures de la pièce en acier nécessaires pour le durcissement ou le traitement par trempe et revenu soient maintenues selon un processus fiable. A cet effet, l'invention prévoit, selon un premier enseignement, des moyens permettant un chauffage inductif, convectif et/ou par rayonnement des pièces en acier.
